摘 要: | 中大型无人机系统具有良好的航程航时性能,其配备的视距数据链的理论作用距离通常可达数百公里,但受限于无线电通视条件,实际作用距离变化显著,影响飞行控制操作和任务完成度。提出了一种无人机视距数据链通视分析方法,利用Global Mapper软件基于地理信息系统(GIS)处理能力,分析在不同飞行高度下的视距地面数据终端与无人机的通视区域,可推广至无人机载荷对地侦察任务区域分析,协助预先和在线进行飞行任务航迹规划,确定空域限制条件。经过实际检验,证明本方法快速高效、符合度高,特别适用于无人机执飞高原和山区等地形地貌复杂区域。

Intervisibility Analysis Method of UAV LOS Data Link |

Abstract: | The medium and large UAV system has good range and endurance performance.The theoretical operating distance of the line of sight (LOS) data link equipped with it can usually reach hundreds of kilometers.However,due to the wireless communication conditions,the actual operating distance changes significantly,which affects the flight control operation and mission completion.A LOS analysis method of UAV LOS data link is proposed,which uses Global Mapper software to analyze the LOS area between ground data terminal and UAV at different flight altitudes based on the processing ability of geographic information system (GIS),which can be extended to the analysis of UAV payload ground reconnaissance mission area,assist in flight mission path planning in advance and online,and determine airspace constraints.The practical test shows that this method is fast,efficient and has high consistency,which is especially suitable for UAV flying in plateau,mountainous area and other areas with complex terrain and landform. |
